Manufacturer's claims: SoilUTION is a two-part product consisting of SoilUTION and SoilUTION-M. SoilUTION is 1-4 mole nonionic surfactant, biocatalyst, and nutrient. The 100 percent biodegradable cleaning agent can be used to remove hydrocarbons and begin the breakdown digestion of hydrocarbon molecules. SoilUTION-M is the same product with the addition of the REM-3 microbes. Both surfactants serve as enhancers to the ProZorb and REM-3 products. SoilUTION contains no chemical degreasers or emulsifiers.
Site maintenance intensity: Easily applied with a liquid sprayer, then mix in. Site maintenance intensity depends on the remediation technique used.
Mobility: In concentrated form, 8.5 pounds per gallon. The manufacturer recommends diluting SoilUTION with water at a 1:1 ratio.
Cold climate applicability: SoilUTION and SoilUTION-M will freeze at 32 °F and boil at 212 °F. It is not recommended that these agents be used as a cleaning method at temperatures below freezing.
Approximate cost to treat a cubic yard: $29.99 per pound. For TPH levels less than 100,000, $3 per cubic yard, $6 per cubic yard if the product is used with REM-3.
Product name: Soil Washing Systems
Product category: Soil washing

Manufacturer's claims: The BioGenesis washing process can be used on all types of gravel, sand, silt, and clay, and can clean soil particles as small as 1 micron. The system can remediate almost all types of pollutants, producing only the original contaminants contained in the soil. The systems use biodegradable, low-toxicity chemicals during the washing process.
Mobility: The washing unit is truck mounted. Excavation and loading equipment is needed. At least 10,000 to 20,000 cubic yards of contaminated soil need to be treated to justify this process.
Cold climate applicability: Best done in periods of warming temperatures. Cleanup period is generally short.
Approximate cost to treat a cubic yard: Estimates ranged from $80 to $170 per cubic yard (assuming more than 5,000 cubic yards of sandy or gravelly soils). This estimate is applicable towards Alaska applications. Soil washing in the lower 48 States costs about half of the estimate for Alaska.
Manufacturer's comments: Separated contaminants will need to be removed or destroyed.

Manufacturer's claims: Thermally processes up to 40 tons per hour of hydrocarbon-contaminated soil. Degrades soils rated up to 50,000 parts per million of contaminants down to nondetectable levels. Much more efficient and economical than similar thermal desorption equipment. System fits on one flatbed semitrailer, including conveyors for soil transfer. Very easy and quick to set up.
Site maintenance intensity: The system requires an operator and a front-end loader with an operator. Continuous automatic monitoring is available for air emissions and particulate. Treated product (soil) samples can be taken periodically.
Mobility: The Klean Machine fits on a 40-foot trailer (highway acceptable) and can be transported by truck, barge, or Hercules aircraft. The system weighs about 39,000 pounds.
Cold climate applicability: The Klean Machine is not affected by cold climate conditions. As long as the soil can be excavated, the machine can work.
Approximate cost to treat a cubic yard: From $40 to $85, depending on the level of contamination.
Manufacturer's comments: Unit has its own generator for power. Onsite demonstration sessions are conducted regularly. Call the manufacturer to arrange an appointment.
Formal research: Test results and studies are available from the manufacturer.
Field users' contacts: Past testimonials as well as a list of past and current users is available from the manufacturer.
